Definitions

  • the intermediate signal may be provided by calculating the autocorrelation of a signal derived from the speech signal by filtering the speech signal through a filter based on a set of filter parameters estimated by means of linear predictive analysis (LPA).
  • LPA linear predictive analysis
  • the best estimate is achieved when the device is adapted to select the sample having the maximum amplitude of said conformity function as the estimate of the pitch.
